Here, the upper hinge 30b of the movable side shoji 11
Will be described. 5 to 8 show the upper hinge 3 attached to the upper end of the (outer) vertical frame 16 of the movable side shoji 11.
It is a figure which shows Ob, respectively, and shows the top view, the figure which shows the engagement state of the upper hinge and an upper frame in the state which opened the folding door shoji, the side view, and the longitudinal cross-sectional view, respectively. In each of the drawings, an upper hinge 30b (hereinafter, referred to as an upper movable hinge) of a movable shoji is rotated around a vertical axis by a housing 32 fitted to the upper end of the (outer) vertical frame 16 of the movable shoji 11. And a rotating shaft 31 that is movable. Rotation axis 3 of upper movable hinge 30b
The lower part of 1 is rotatably accommodated in the circular hole 32a of the housing 32, and the upper part protrudes above the housing.

At the upper end of the rotating shaft 31 of the upper movable hinge, there is formed an engaging groove 31a which extends longitudinally in the radial direction, and the engaging groove 31a of the rotating shaft is loosely formed on the guide rail 1a of the upper frame. Engage. As shown in FIG. 6, the engagement between the engagement groove 31a and the guide rail 1a causes the rotating shaft 31 to slide on the guide rail 1a of the upper frame while rotating with respect to the movable side shoji 11 and move. The side shoji 11 can be opened and closed freely.

A coil spring 33 is provided below the rotating shaft 31 of the upper movable hinge, and the coil spring 33 urges the rotating shaft 31 upward. By applying a downward force to the rotating shaft 31, the coil spring 33
, The rotating shaft 31 can be moved downward. At the lower end of the rotation shaft 31, a rotation shaft 31 is provided.
An engagement claw 31b that locks to the housing 32 is formed to prevent the projection 32 from jumping upward. When no vertical force is applied to the rotation shaft 31, the engagement claw 31 b is locked to the lower surface of the housing 32 by the action of the coil spring 33.

Here, the housing 32 of the upper movable hinge 30b and the shoji slip stopper 34 will be described. 9 and 10
Is a view showing a housing 32 of the upper movable hinge 30b, and shows a plan view and a longitudinal sectional view, respectively. 11 to
FIG. 13 is a view showing the shoji stopper 34 of the upper movable hinge 30b, which shows a plan view, a front view, and a side view, respectively. In each of the figures, a guide groove 32b is cut out along the longitudinal direction of the upper frame 13 of the movable sash 11 as shown in FIG. 9 in the housing 32 of the upper movable hinge 30b. In the vicinity of the circular hole 32a of the guide groove 32b, a hook portion 32c having a reduced groove width is provided. On the other hand, the shoji slip stopper 34 of the upper movable hinge 30b is formed in a substantially flat plate shape, and a guide piece 34a projecting downward and substantially in a U-shape is provided below it. The guide piece 34a is inserted into a guide groove 32b provided in the housing 32 and guided.

The shroud stopper 34 of the upper movable hinge is attached to the housing 3
2 and the guide piece 34a of the shoji stopper 34 is guided in the guide groove 32b of the housing 32, so that the shoji stopper 34 is
3 is movable in the longitudinal direction. FIG. 14 is a cross-sectional view of a state in which the folding door shoji is folded. In this folded state, the longitudinal direction of the upper frame 13 of the movable-side shoji 11 and the longitudinal direction of the upper frame 1 are substantially orthogonal. By inserting and guiding the guide piece 34a of the stopper 34 into the guide groove 32b of the housing 32, the sash slipper stopper 34 can be freely inserted and removed between the housing 32 and the guide rail 1a of the upper frame as shown in FIG. can do.

On the other hand, in the closed state shown in FIG. 2, since the longitudinal direction of the upper frame 13 of the movable side shoji 11 and the longitudinal direction of the upper frame 1 are substantially parallel, the shoji stopper 34 is always attached to the housing 3.
2 and the guide rail 1a of the upper frame. Therefore, no matter how much the folding door shoji is lifted as described later, it is possible to prevent the folding door shoji from coming off the frame due to the collision of the shoji stopper 34 with the guide rail 1a of the upper frame.

If the stopper 34 of the upper movable hinge 30b is further moved toward the circular hole 32a than the hook 32c of the guide groove 32b, the U-shaped portion of the guide piece 34a of the stopper 34 will be described. The guide piece 34a is elastically actuated.
Is loosely locked to the hook portion 32c of the guide groove 32b, so that the sash slipper stopper 34 can be loosely fixed to the housing 32. If the shoji stopper 34 is fixed to the above position, the housing 32 is always in the open state and the closed state.
And the guide rail 1a of the upper frame can be provided with the sash slipper stopper 34, so that the folding door sash can be effectively prevented from coming off the frame.

The thickness of the shoji stopper 34 depends on the distance between the guide rail 1a of the upper frame and the upper hinge 30 and the lower hinge 35.
Is determined by the relationship with the engagement groove 36a provided in the rotation shaft 36 of FIG. That is, the thickness of the shoji slip stopper 34 is
The height H1 from the upper surface of the shoji stopper 34 to the guide rail 1a of the upper frame when the shoji stopper 34 is inserted between the upper movable hinge 30b and the guide rail 1a of the upper frame is the rotation axis 36 of the lower hinge. Is smaller than the engagement distance of the engagement groove 36a. The engagement distance refers to a distance by which the folding door shoji can be lifted up while holding the engagement between the engagement groove 36a of the rotation shaft 36 of the lower hinge and the guide rail 2a of the lower frame. (The height H2 of the engaging groove of the rotating shaft) + (the play H3 of the rotating shaft against the folding door shoji). In addition, the play H3 of the rotating shaft against the folding door shoji is equivalent to the first restricting portion 3 of the rotating shaft 36 described later.
6b and the distance between the lower hinge and the upper surface of the housing 37 in a state where the folding door is installed.

Thus, in a state where the shoji stopper 34 is inserted between the upper movable hinge 30b and the guide rail 1a of the upper frame, no matter how much the movable shoji 11 is lifted up, the pivot axis of the lower hinge can be increased. Before the engagement groove 36a of 36 disengages from the guide rail 2a of the lower frame, the sash slipper stopper 34 collides with the guide rail 1a of the upper frame, so that the movable side sash 11 cannot be lifted any further. Therefore, as long as the shoji stopper 34 is inserted between the upper movable hinge 30b and the guide rail 1a of the upper frame, the engaging groove 36a of the rotation shaft 36 of the lower hinge is disengaged from the guide rail 2a of the lower frame. There is nothing. on the other hand,
In the state where the shoji stopper 34 is not inserted between the upper movable hinge 30b and the upper frame guide rail 1a, there is a height of only H4 between the upper movable hinge 30b and the upper frame guide rail 1a. As described above, it is possible to secure a working space for engaging the lower hinge 35 with the guide rail 2a of the lower frame when the folding door shoji is attached.

The upper hinge 30a of the stationary side shoji 10 (hereinafter, referred to as the upper hinge 30a)
It is called upper fixed hinge. ) Also for the upper movable hinge 30b
Since the configuration is similar to that described above, the description is omitted. Note that the engaging groove of the rotating shaft of the upper fixed hinge 30a does not extend longitudinally in the radial direction, and the engaging groove engages with the cutout portion of the guide rail 1a of the upper frame, so that the fixed side shoji 10 The point that the rotating shaft is fixed is different from the upper movable hinge 30b.

Next, the lower hinge 35b of the movable side shoji 11 will be described. FIGS. 15 to 18 are views showing the lower hinge 35b attached to the vertical frame 16 of the movable side shoji 11, showing the engagement state between the lower hinge and the lower frame when the folding door shoji is closed, and a bottom view. , Side view and longitudinal section. In each figure, the lower hinge 35b of the movable side shoji is shown.
(Hereinafter, referred to as a movable lower hinge) includes a housing 37 fitted to the lower end of the (outer) vertical frame 16 of the movable side shoji 11, a rotating shaft 36 which is rotatable about the vertical direction. , Is provided. The upper part of the rotating shaft 36 of the lower movable hinge is
7 is rotatably accommodated in the circular hole 37 a, and the upper part thereof protrudes below the housing 37.

At the lower end of the rotating shaft 36 of the lower movable hinge, there is formed an engaging groove 36a which extends longitudinally in the radial direction, and the engaging groove 36a of the rotating shaft is loosely engaged with the guide rail 2a of the lower frame. Combine. The configuration of this engagement is the same as that of the above-mentioned upper movable hinge 30b. Here, a first restricting portion 36b is formed at the upper end of the rotating shaft 36 to prevent the rotating shaft 36 from dropping below the housing 37. The downward movement of the rotation shaft 36 is restricted by being locked to the upper surface of the rotation shaft 36. When no vertical force is applied to the rotation shaft 36, the first restricting portion 36 b is locked to the upper surface of the housing 37 by the weight of the rotation shaft 36.

Further, a pedestal-shaped second restricting portion 36c is formed below the first restricting portion 36b of the rotating shaft.
A step is provided by forming the upper portion of the circular hole 37a of the housing 37 of the lower movable hinge with a different diameter. The second restricting portion 36c locks a step above the circular hole 37a of the housing to restrict the upward movement of the rotating shaft 36. In a state where an upward force is applied to the rotating shaft 36, the second restricting portion 36c is connected to the circular hole 37a.
To the step. Even when the guide rail 2a of the lower frame is engaged with the engagement groove 36a of the rotating shaft of the lower movable hinge 35b,
The second restricting portion 36c of the rotating shaft 36 is locked at the step of the circular hole 37a.

The lower hinge 35a of the stationary side shoji 10 (hereinafter, referred to as the lower hinge 35a)
It is called the lower fixed hinge. ) Also applies to the lower movable hinge 3
5b, but the engaging groove of the rotating shaft of the lower fixed hinge 35a does not extend longitudinally in the radial direction, and the engaging groove engages with the notch of the guide rail 2a of the lower frame. This is different from the lower movable hinge 35b in that the rotation axis of the fixed side sash is fixed.

FIG. 19 shows a comparison between the lower hinge of the movable sash and the lower hinge of the fixed sash. The rotation axis 36 of the lower movable hinge 35b and the rotation axis 3 of the lower fixed hinge 35a are shown in FIG.
6 is different in length. That is, the lower movable hinge 3
From the first restricting portion 36b of the rotating shaft 36 of FIG.
The distance h2 from the first restricting portion 36b of the rotating shaft 36 of the lower fixed hinge 35a to the engagement groove 36a is longer than the distance h1 to a. Therefore, both rotating shafts 36, 36
When no force is applied, the first restricting portions of the rotating shafts of the lower hinges 35a and 35b are locked to the upper surface of the housing. At this time, the engagement groove of the rotating shaft of the lower fixed hinge 35a is positioned lower than the engagement groove of the rotating shaft of the lower movable hinge 35b.

On the other hand, the distance h3 from the second restricting portion 36c of the rotating shaft of the lower movable hinge 35b to the engaging groove 36a is determined by the distance from the second restricting portion 36c of the rotating shaft of the lower fixed hinge 35a to the engaging groove 36a. It is formed so as to be substantially the same as the distance h4 to. Therefore, when the lower hinges and the rails of the lower frame 2 are engaged with each other, the second restricting portions 36c, 36c of the both rotating shafts are engaged with the step of the circular hole 37a of the housing 37 by the weight of the folding door shoji. Stop. At this time, both lower hinges 35
a and 35b are kept at the same height, and the entire Orito Shoji can be supported horizontally.

Next, a procedure for attaching the movable side shoji 11 and the fixed side shoji 10 to the frame will be described. First, connecting frame 12
The movable side sash 11 and the fixed side sash 10 connected by the above are folded by the connection frame 12. In this folded state, the upper movable hinge 30b and the upper fixed hinge 30a are not yet fixed to the housing 32 with the sash slipper stopper 34. Next, the direction of the engaging groove of the rotating shaft of the upper fixed hinge 30a is aligned with the guide rail 1a of the upper frame, and the engaging groove is locked in the notch of the guide rail 1a of the upper frame, so that the upper fixed hinge 30a Is fixed to the guide rail 1a of the upper frame. Similarly, the direction of the engaging groove 31a of the rotating shaft of the upper movable hinge 30b is aligned with the guide rail 1a of the upper frame, and the engaging groove 31a is engaged with the guide rail 1a of the upper frame, so that the upper movable hinge 30b Is slidable on the guide rail 1a of the upper frame.

Next, the folding door sliding doors 10 and 11 are lifted upward, and the lower hinge 35 is engaged with the guide rail 2a of the lower frame. In this state, the stopper 34 of the upper hinge 30 is still engaged with the upper hinge 30. And upper frame guide rail 1a
Between the upper hinge 30
There is a sufficient space between the guide rail 1a and the upper frame. Therefore, it is possible to provide a sufficient space between the lower hinge 35 and the lower frame 2 for engaging the lower hinge 35 by lifting the folding door shojis 10 and 11.

Here, both lower hinges 35a and 35b are engaged with the guide rail 2a of the lower frame. As described above, the engagement groove of the rotating shaft of the lower fixed hinge 35a is fitted to the lower movable hinge 35b. Is located below the engagement groove of the rotating shaft. Therefore, the direction of the engagement groove of the lower fixed hinge 35a, which is closer to the guide rail 2a of the lower frame, can be checked first, and it can be easily engaged with the guide rail 2a of the lower frame.
After the lower fixed hinge 35a is engaged in this manner, when the folded folding door is slightly lowered, the engagement groove of the rotating shaft of the lower movable hinge 35b is positioned exactly near the guide rail 2a of the lower frame. be able to. Therefore, it is possible to confirm the direction of the engagement groove of the rotating shaft of the lower movable hinge 35b and to engage with the guide rail 2a of the lower frame. As described above, since each of the lower hinges 35a and 35b can be engaged with the guide rail 2a of the lower frame, attachment of the folding door shoji becomes easy.

Thus, the mounting of the folding door shoji on the frame is completed. At this time, when the mounting is completed, the shoji stopper 34 of the upper movable hinge 30b and the upper fixed hinge 30a is moved to the circular hole 32a side of the housing 32, so that the shoji stopper 34 is connected to the upper hinge 30 and the guide rail of the upper frame. 1a. As a result, no matter how much the Orito Shoji is lifted, it does not come off the frame.

While one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and may be embodied in various forms within the scope of the technical idea. Although the lower hinge in the present embodiment is configured to be movable vertically,
The lower hinge may be fixed to the folding door shoji. In this case, the engagement distance of the rotation axis of the lower hinge is the height of the engagement groove of the movable sash of the lower hinge.

[0035]

As described above, according to the present invention, the upper and lower frames
A rail is provided along the longitudinal direction of the upper and lower frames, and upper hinges for rotatably and / or slidably supporting the folding shoji on the upper and lower ends of the vertical stiles at the left and right ends of the pair of folding shoji. Or, a lower hinge is provided, and the upper hinge is capable of moving in the vertical direction and rotating about the vertical direction,
By providing a housing for accommodating the rotating shaft and a shoji slipper that can be freely inserted and removed between the housing and the rail of the upper frame,
Since the height from the upper hinge to the rail of the upper frame can be adjusted at the time of mounting the folding door shoji and after the mounting, the height is increased at the time of mounting to facilitate the mounting of the folding door shoji, and the height after the mounting is increased. By reducing the height, it is possible to prevent the folding door shoji from coming off the frame.

Further, a guide piece projecting downward is provided in the upper hinge to prevent the sliding door from coming off, and a guide groove is provided in the upper hinge so that the guiding piece for the sliding door can be guided in the longitudinal direction of the upper frame of the folding door. By setting up, it is possible to attach the folding door shoji to the frame in the state where the folding door shoji is folded,
There is an effect that mounting in a compact state becomes possible.

The lower hinge is provided with a rotating shaft that is rotatable about the vertical direction, and the rotating shaft of the lower hinge is provided with an engaging groove that engages with the rail of the lower frame. The height of the upper frame from the upper surface to the rail of the upper frame is made smaller than the engagement distance of the engagement groove of the rotation shaft of the lower hinge, so that the upper frame and the upper frame can be removed after installation. When the folding door is inserted between the two rails, even if the folding door is raised to the maximum, the sash slippage stopper is caught on the rail of the upper frame, so that there is an effect that the engagement between the lower hinge and the lower frame rail does not come off.

The lower hinge pivot shaft has an engagement groove for engaging the rail of the lower frame, a first regulating portion for regulating the downward movement of the pivot shaft relative to the hinge, and a pivot relative to the hinge. A second restricting portion for restricting the upward movement of the driving shaft,
By making the distances from the first restricting portions of the left and right lower hinges to the engaging grooves different from each other and making the distances from the second restricting portions to the engaging grooves substantially the same, when attaching the folding door shoji, Since there is a difference in the distance between the lower hinge housing and the engagement groove of the rotation axis of the lower hinge, there is no need to engage the left and right lower hinges simultaneously when engaging the lower hinge with the rail of the lower frame. There is an effect that mounting becomes easy. further,
After the mounting, the distance between the housing of the lower hinge and the engagement groove of the rotation axis of the lower hinge becomes the same, so that there is an effect that the folding door shoji after the mounting can be held horizontally.
